Question

How tell me how you got answer 5.9 and also if you do at calculate can show me how to do pls thanks.

Answer 1

The steps you have are correct. I'll fill in the gap between step 2 and step 3.

`0.4245 = \frac{2.5}{\text{x}}\\\\0.4245\text{x} = 2.5\\\\\text{x} = (2.5)/(0.4245)\\\\\text{x} = 5.8892815\\\\\text{x} = 5.9\\\\`

I multiplied both sides by x, then divided both sides by 0.4245 to isolate the variable.

With the exception of 2.5, every other decimal value mentioned is approximate.
